Marco Massenzio created MESOS-4253: -------------------------------------- Summary: Provide a minimalist "runtime context" to an Anonymous Module Key: MESOS-4253 URL: https://issues.apache.org/jira/browse/MESOS-4253 Project: Mesos Issue Type: Improvement Components: modules Reporter: Marco Massenzio Assignee: Marco Massenzio
Currently, {{Anonymous}} modules only receive at creation a copy of the {{"parameters"}} passed in the JSON configuration file. However, at runtime, it would be useful to also have a "runtime context" for the module developer to use, when implementing the functionality. I would suggest to pass in the {{Flags}} object from the Master/Agent inside an {{setRuntimeContext(const Flags&)}}[0] method, called immediately post-{{create(const Parameters&)}}[1]. Also, I would suggest adding a {{teardown()}} method too, in case the module needs to release resources / conduct cleanup before exiting (there is a TODO in the code to this effect, and adding this in this patch would be close to trivial). [0] In practice, it won't be this trivial, as Master/Agent {{Flags}} are of a different compile-time type - probably use something like variadic templates or something (suggestions appreciated!). [1] In fact, the ideal solution would be to add the {{const Flags&}} to {{create()}}, but that would, alas, break everyone's modules; so that's probably a no-go (ideas welcome here too). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
